Cuz I'm gonna be feastin' on anti-inflammatories for the next few days... (((ACK ACK HEART ATTACK!!!)))
The secret to perfectly caramelized roasted veg is to roast them in a thin layer at a high temp (400), and flipping them around often. Coat even sized pieces of sweet potato in olive oil and salt, roast for about an hour, giving them a flip every fifteen minutes or so.
After an hour, add garlic (I used minced - if you use whole just add it about 15 minutes earlier) and herbs (I used poultry seasoning, cuz I'm original like that) and roast for another 10 to 15 minutes at a slightly lower temp. All this effort is for not if you burn your herbs, dudes.
And voila! Fab side dish, burrito filling, midnight snack, breakfast, etc etc. Try it.
